Struct boolean_expression::PersistedBDD

pub struct PersistedBDD<T> where
    T: Clone + Debug + Eq + Ord + Hash,  { /* fields omitted */ }

A PersistedBDD is a wrapper around a BDD that provides a means to write BDD labels and nodes out to a BDDOutput. It tracks how much of the BDD has already been writen out, and writes out new nodes and labels as required when its persist() or persist_all() method is called.

Methods

impl<T> PersistedBDD<T> where     T: Clone + Debug + Eq + Ord + Hash,

pub fn new() -> PersistedBDD<T>

Create a new PersistedBDD.

pub fn bdd(&self) -> &BDD<T>

Return the inner BDD.

pub fn bdd_mut(&mut self) -> &mut BDD<T>

Return the inner BDD.

pub fn persist<E>(&mut self, f: BDDFunc, out: &BDDOutput<T, E>) -> Result<(), E>

Persist (at least) all labels and nodes in the BDD necessary to fully describe BDD function f. More records than strictly necessary may be written out.

pub fn persist_all<E>(&mut self, out: &BDDOutput<T, E>) -> Result<(), E>

Persist all labels and nodes in the BDD.
